Challenge / Goal

Public space is a rare resource. Currently, private cars take a lot of public space as they are parked, on average, 23 hours a day. In the inner city of Berlin, less than half of the households have a car. The SrV (System of Representative Traffic Surveys) found that the majority of daily trips, roughly 82%, are made by foot, bicycle or public transport. Therefore, the question arises how public space can be designed to benefit as many people as possible and promote active mobility.                                      
The location of the street experiment is characterized by a large traffic area, on which there is a small square. This space has hardly been used for activities other than parking cars. The goal of this project is to explore how changing traffic patterns enable new uses of public space.


Through the partial closure of a traffic intersection for five weeks, a new city square was generated.  Alternative parking options (underused supermarket parking spaces) have been provided for the eliminated parking spaces. The creation of a pedestrian zone temporarily changed the traffic rules in parts of "Wundtstraße" and "Horstweg" in Berlin-Charlottenburg. For the duration of the project,  various elements were provided that invited people to stay and use the free space in a new way. On the city square there were freely accessible seating options, a table with chairs, deck chairs, wooden benches and hammocks, as well as a play box with badminton, basketball, football, skipping ropes and street chalk.

Citizen participation

1)Household survey to inform residents and to get their opinion about the temporary city square.  
2)On-site survey with residents, users of the city square and passers-by.  
3)Open meetings with residents (children and adults) for exchange of opinions and discussion.  
4)Voting on design proposals, which were published at the beginning of the project.  
5)Participation of residents at the construction of square furniture and at activities that have taken place at the city square (Tree slice greening, flea market, children's games, music and cultural events)
